Gotcha. Yes these are with .25 Altaros ATP Smooth 49.5 grain. BC with G1 or RA4 is 0.21. I use equivalent G7 which gives a lower number of around 0.110. Never paid much attention to BC “spreads”. Same slug, same speed, same distance. Any deviations are from weather and wind conditions. The Altaros IMHO are by far the best slugs on the market.
I have some and have shot a bit with them and they are very promising. They exposed a ton that was wrong with my FX Maverick. I went through 2 packs fixing like 5 different things - hammer, hammer spring, tensioner muzzle, and finding balance between reg pressure and hammer weight. I went back to .30 on the maverick and I'm not sure I want to spend any more time tuning it for .25. I think the better thing for me to do is get a dedicated .25 rifle that can comfortably shoot the ATP Queens at 950 FPS and the maverick aint it.
FYI. The Altaros Queens are much more accurate from 850 to 900 fps. And with a G1 BC of 0.245, what more do you need?
My teammate Augie @Bigragu turned me on to this last year. With this and an ARCA rail, you don't need additional weights on your gun. This sucker is HEAVY!!! It is ROCK SOLID.
My initial thought is that the juice isn't worth the squeeze, since with the 49.5 grain Smooth your BC is already almost twice any other conventional slug. That being said, I have a 700mm FX Slug 1:16 liner that I plan to install in my Impact and see how the Queens do at about 875 to 880 fps. Just for the halibut...
idk, i figured part of the reason behind the big spread i was getting on BC had to do with smooths being 6.35 and FX preferring 6.36 which the queens come in. Also i just love power
